    Rationale

    ASTM A957/A957M contains product tolerance analysis limits for carbon and low alloy steels and for stainless steel. This work item adds product tolerances for nickel and cobalt based alloys. The table is identical to the one recently added to ASTM A703/A703M. It is also similar to the table in ASTM B880 except for a change to the silicon allowances.
